Drinking Bloody Marys isn’t just a brunch-time pursuit ­— the tomato cocktail is also perfect for Halloween. This year marks the 80th anniversary of the French drink’s arrival in the US by way of the St. Regis’ elegant King Cole Bar (2 E. 55th St.).

While various origin stories swirl around the cocktail, most believe the beverage was named after Queen Mary I of England, a notoriously murderous royal who had 280 religious dissenters burned at the stake.

At first, the St. Regis changed the drink’s name to the Red Snapper because Bloody Mary “was considered too vulgar,” explains Mike Regan, a bartender at the hotel. Now, sensibilities are not so delicate, and it’s a Bloody Mary again.
